ROBERT OGDEN, OF MANCHESTER, AND ROBERT JAMES ANDERSON, OF LIVERPOOL. COUNTY OF LANCASTER, ENGLAND.

LAMP-EXTNGUISHER.

SPECIFICATIN forming part of Letters Patent No. 296,771, dated April l5, 1884.

Application filed November 7, i883. (No model.) Patented in England February 6, 18815, No. 657.

To @ZZ whom t may concern:

Beit known that we, ROBERT OGDEN, of Manchester, and ROBERT JMEs ANDnnsoN, of Liverpool, both in the county of Lancaster,

' England, have invented a certain new and useful Improvement in Lamps, (for which we have obtained a patent in Great Britain, No. 657, bearing date February 6, 1883,) of which the following is a specification.

Our invention relates to an iniprovernentin lamps, and is applicable to all kinds of movable lampswhether carried by hand or otherwise, and the object of our invention is to extinguisb the light or lights of a lamp automaticallyif theialnp be upset or moved sufciently out of the perpendicular, thereby preventing accidents, such as explosion or tire.A Ve attain this object by the mechanism illustrated in the accompanying four sheets of drawings, in which- Figure 1 is an elevation of a lamp to which our improvement is applied. Fig. 2 is an elevation with part of the frame removed, and Fig. 3 a plan of a burner iitted with our improvement. 4 is a detached View of a spring trigger or catch. Fig. 5 is an elevation,

' with part oi' the frame removed, of a burner in which a weighted lever is used instead of a spring-catch, and Figs.`6 and 7 are detached views of the weighted lever. Figs. 8 and 9 are side views, and Fig. l() a plan of a modiiication of our invention. Figs. 1l and 12 are two views of another modification, and Fig. 13 is a detached view of the upper spindle, d, and disk d.

Similar letters refer to similar parts throughout the several views.

In Figs. l to 4c, a is au ordinary table-lamp, with a duplex or other burner, b, tted with sliding extinguishers c. A small vertical spindle, el, passes through the center and lower part of the burner?) into the oil-reservoir. A small metal disk, fl', is secured to the bottom of the spindle Below and in Contact with the disk dA is another and similar disk, e, secured to the upper end of a spindle, e', which is weighted at the other end, e?, and suspended by nie-ans of a ball, e3, in a bracket, f, attached tothe lower portion of the burner. The weighted spindle e is thus free to swing in any direction.

To allow the lamp to be lighted, the sliding extinguishers c are lowered in the ordinary manner by the lever g, which is pivoted to the frame at g', and to which a spring, g2, is attached to close the extinguishers o when required. The end of this lever g is then caught and held byasuiall trigger, h, (shown detached in Fig. 4,) fitted with a spring, h', to hold the trigger over the end of thelever g, and pivoted to the frame at hi. This trigger h is immediately over the spindle d and disk d', acted on by the disk e and weighted spindle e.

If the lamp, when burning, is upset or inclined to a sufficient angle, the weighted spindle e and lower disk, e, swing in the ball-andsocket or universal joint and raise the upper disk, d, and spindle d, thus raising one end of the trigger h and releasing the lever g. The spring g'i is then left free to close the eXtin guishers c and put out the light. The angle at which the trigger acts to release the lever g, and thus cause the light to be extinguished, may be adjusted and set to any degree desired.

Figs. 5, 6, and 7 represent a modification of our invention in which a weighted lever, 1'., with a catch, fi, is employed in place of the trigger h., thereby dispensing with the springh. In the arrangement shown in Figs. 8, 9, and

10 neither the spring gi, spring-trigger h, nor

its equivalent, the weighted lever t', are employed; but the sliding spindle l is bent near the upper end and acts directly upon thelower side of the lever y at a point near the pivot g', so as toraise the end of the lever g sufficiently to slide the extinguishers c, and thus put out the light, when the lamp is tilted or upset. The dotted lines indicate the relative positions which the weighted spindle, disks, and extinguishers would occupy if the lamp were upset or tilted to one side.

In Figs. 11 and 12 the bracket f is shown secured to the collar ci of the lamp, instead of to the burner Z2, as previously represented. This arrangement enables us to use larger disks, and is also more convenient, as the weight is not removed from the lamp when the burner is lifted out to renew the wicks, iill the oilreservoir, or for other'purposes.

It may be mentioned with reference to each of the foregoing arrangements that the act of lowering the extinguishers, o by means of the IOO lever g preparatory to lighting the lamp is sufl said trigger, and provided at its lower end with ieient to set the automatic extinguishing meehanism.

Having stated the nature of our invention 5 and described the manner of performing the same, We would have it understood that what We claim, and desire to seeure by Letters Patent of the United States, is-

The combination of a sliding extinguisher io with a lever, g, for raising and lowering the same, the spring g, which operates said lever to automatieally raise said extinguisher forv allowing the same to close, the spring-pressed trigger 7L, which normally holds said lever out I5 of operation, the spindle d, arranged below a disk, d', and the weighted spindle e, having at its upper end a disk, e, inv Contact Withsaid disk d', for the purpose set forth.

The foregoing speeieation of our improve- `2o nient in lamps signed by us this 26th day of October7 1883.
